Ecological changes in aquatic communities in the Big Bend reach of the Rio Grande: Synthesis and future monitoring needs
There is a need to understand how alteration of physical processes on the Rio Grande River have impacted aquatic biota and their habitats, and a need to predict potential future effects of climate change on biotic resources in order to prescribe research and management activities that will enhance conservation of aquatic species. We propose a project with the goal of developing monitoring recommendations and identifying research needs for aquatic ecological resources in the Big Bend region of the Rio Grande. This goal will be targeted by synthesizing and analyzing available data and literature for aquatic species in the project region. In particular, we will work to develop time series of abundance and population...
Final Report: Data provision and projected impact of climate change on fish biodiversity within the Desert LCC
The four primary objectives of this project were to: (1) compile a dataset of fish occurrence records for the entirety of the Rio Grande drainage in the US and Mexico; (2) improve that dataset by reformatting dates, synonymizing species names to a modern taxonomy, georeferencing localities, and flagging geographic outliers; (3) for those species with sufficient data for modeling, create species distribution models (SDMs); (4) use the environmental conditions determined via those models to project the species distributions into the future under two climate scenarios. To accomplish those objectives, we compiled 495,101 fish occurrence records mined from 122 original sources into a single database. We then, on the...
**Executive Summary: **The Big Bend reach of the Rio Grande is an important region for binational collaboration on ecosystem management and restoration. The river is well protected from further development as a national wild and scenic river and by national and state parks on both sides of the border, but has been degraded over time primarily by altered hydrology, water quality degradation, and non-native species impacts. The success of future restoration and management efforts depend on a fuller understanding of the linkages between physical and chemical processes and biotic communities. A robust monitoring program in the region and targeted research are needed to supply this understanding. In this report, we synthesize...
